1 Claim.

This invention relates to improvements in snow plows and is directed more particularly to improvements inside wings or guides for snow plows.

The novel objects of this invention are directed to the provision of a side wing or guide which is adapted for attachment to a plow construction and arranged to cooperate therewith for plowing operations.

A plow of the type to which the invention relates is usually attached to a vehicle by wh ch it is pushed and as it acts against the snow the 'forward leading edge or end of the plow blade acts on the snow in such a way as tends to cause the plow to urge the vehicle diagonally from a straight path. In other words, the leading edge of the plow blade tends to climb diagonally into the snow and is very objectionable.

According to this invention, we provide a side wing arranged to be associated with a plow structure that is adapted to act on the snow at the side of the groove formed by the plow and prevent the objectionable action mentioned.

The novel features of the invention are adapted for broad application to plow structures of different kinds but as a special feature the guide wing structure of the invention is adapted for use in connection with a plow structure, having a diagonally disposed plow blade that is pushed along by a vehicle.

Various novel features and advantages of the invention will be observed from the following description thereof in the form at present preferred.

In the drawing:

Fig. 1 is a plan view of the side wing guide construction of the invention shown in association with a plow structure; and

Fig. 2 is an elevational view of the construction shown in Fig. 1.

Referring now to the drawing more in detail, the invention will be more fully described.

A plow construction is shown which includes a plow blade disposed in a vertical plane that is carried by frame members 4 that provide a supporting frame. These members 4 are secured together by cross members and are in various ways secured together so as to form a strong rigid structure adapted to be connected to the forward part of a vehicle such as a truck so that as the truck moves forwardly the plow blade acts to push the snow. The blade being on an angle the snow is pushed to the right. Of course, the blade may be disposed in any other angle desired.

As previously stated, there is a decided tendency for the leading edge of the blade to dig into the snow diagonally to the left and act on the propelling vehicle in such a way that it runs from off a straight path.

The plow blade shown is of the stationary type but the invention is useful in connection with plows where the blade swings or is known as the tri -type blade.

A side wing guide 6 is provided which is mounted on supports that are attachable to the plow support in such a manner that the plane of the guide is disposed verticall and parallel to the path of movement of the vehicle. The forward end of the guide is closely adjacent to the leading edge of the plow blade and where desired the adjacent edges of the guide and plow blade may be secured together.

The guide 6 may be made from any material 4 suitable for the purpose and while shown as being constructed from wood or planking it may be a steel plate,

Reinforcing members 8 are carried by the guide 8 and front and rear supporting structures It) and l 2 extend from the guide reinforcing members 8.

The front supporting structure includes a lower member l4 and an upper relatively angularly disposed strut IS. The end of the strut and member M are secured together by means of an angle plate and screws or bolts 22. The upper end of the strut I6 is secured to the reinforcing member 8 by means of an angle plate 24 and screws 26.

The rear supporting structure includes a lower member and an upper strut 32 with the lower end of the strut secured to member 30 by means of an angle plate 34 and screws 36. The upper end of the strut 32 is secured to the reinforcing member 8 by means of an angle plate 38 and screws or bolts 40.

Outer ends of the members l4 and 30 are secured to their respective reinforcing members by means of angles such as 42 and suitable screw or bolts.

A secondary strut 44 has its forward end secured to the guide 6 and its rear free end is adapted to abut one of the members 4 of the plow supporting frame.

The lower members 14 and 30 of the front and rear supporting structures are provided with openings which receive bolts 48 or screws engaging the supporting members for the plow. The free end of the secondary strut is provided with an opening for a screw o bolt 50 engageable with a plow support member 4.

By the means described the wing guide structure is secured to the supports for the plow in such a way that the member 6 is held in a substantially vertical plane and parallel to the support members 4, it being desired that said member 6 be positioned parallel to the direction of movement of the vehicle which carries and pushes the plow.

In this way the member 6 functions to slide along the side or wall of the snow path and prevents the leading edge of the plow blade from digging into the snow so as to urge the plow blade to the left.

The supporting structures with the member 6 provide a unitary structure and facilitate the ready and easy attachment of the unit to and removal thereof from the plow structure.

The supporting structures I and i 2 are arranged in spaced angular relation so that pressure against the guideway is resisted and particularly the forward supporting structure resists inward and rearward pressure at the forward end of the member 8.

The upper and lower members of the structures I0 and I2 are arranged to support the member 6 in its vertical position and the secondary strut cooperates with the other supports to hold the member 6 in position and resist pressure.

There may be a plate 52 at the leading edge of the plow blade when desired which will cooperate with the member 6.

As previously stated, the parts may be made from various materials such as wood. metal. plate structural shapes, etc.. it being intended that the member 6 and associated parts be secured together to provide a unitary structure for securing to and cooperating with a plow structure.

The invention may be embodied in other speciflc form without departing from the essential characteristics thereof. Hence, the present embodiments are therefore to be considered in all respects merely as being illustrative and not as being restrictive, the scope of the invention being indicated by the appended claim rather than by the foregoing description. and all modifications and variations as fall within the meaning and purview and range of equivalency of the appended claim are therefore intended to be embraced therein.

a side wing and What it is desired to claim and secure by Letters Patent of the United States is:

A unitary snow plow construction comprising in combination, outer and inner transversely spaced horizontally disposed longitudinal frame members, the forward end of the inner frame member extending beyond the forward end of outer frame member, a plow blade at the forward ends of the frame members disposed in a substantially vertical plane extending obliquely relative to said frame members having a leading edge disposed at a side of and forwardly of the end of the inner frame member and a trailing edge disposed at a side of and rearwardly of the forward end of the outer frame member, a side wing spaced from and in parallelism with the inner frame member disposed in a vertical plane having a forward leading edge disposed adjacent the leading edge of the said blade, spaced vertically disposed reinforcing members secured to a side of the side wing adjacent the inner frame member, a forward support member secured to the frame members spaced rearwardly from and disposed substantially in parallelism with the plow blade and having an end portion extending outwardly from the inner frame member secured to one of said reinforcing members, a rear support member disposed rearwardly of the forward support member and transversely secured to the frame members having an end portion extending outwardly from the inner frame member and secured to a reinforcing member, strut members above said support members each having one end secured to the support members intermediate the ends thereof and opposite ends secured to the reinforcing members to which the support therebelow is secured, said strut members extending angularly and upwardly from said support to said reinforcing members, and a secondary strut disposed substantially horizontally and obliquely between the inner frame member and side Wing having one end secured to the inner frame member and its other end engaging the a reinforcing member therefor.
